I liked the idea of having some fingerless mittens with full finger mobility, so these are a bit shorter than some of my other fingerless mittens. But, they don’t have to be. If you’d like to lengthen the upper section, so that your fingers have more coverage, it’s as simple as can be - merely add some more 3-row repeats of the plain chevron motif before starting that upper striped motif.

Sample shows bottom edge folded inside at the picot line and hemmed; but, if you prefer, you can leave the bottom edge rolled up, un-hemmed.

Note that the ball band gauge on Alpakka was 25 sts per 4” / 10cm (a sport weight gauge) yet the mittens were knit at 36 sts per 4” / 10cm (a fingering weight gauge). You’ll want to choose either a soft, very lofty yarn with a sport weight gauge close to Alpakka’s ball band gauge of 25, and knit it with smaller-than-ball-band needles (as indicated in the pattern) so that it forms a warm, dense, durable - but even - fabric at 36 sts per 4” / 10cm, or choose a fingering weight yarn, realizing that it won’t be as compressed as the sport weight choice.
